The aim of this study was to test the hypothesis that long-term fetal valproic acid (VPA) exposure at doses relevant to the human clinic interferes with normal brain development. Pregnant rats were given intraperitoneal injections of VPA (20mg/kg or 100mg/kg) continuously during the last 9-12 days of pregnancy and during the lactation period until sacrifice(More)
OBJECTIVE Prenatal exposure to valproic acid (VPA) enhances the risk for later development of autism spectrum disorders (ASD). An altered gamma-aminobutyric acid (GABA) system may be a key factor in ASD. Here we investigated possible changes in the GABA system in rats exposed to a low dose of prenatal VPA. METHOD We performed autoradiography with(More)
In the present study we assessed alterations in cognitive functions in a chronic mild stress (CMS) rat model of depression. Cognitive functions were assessed in two different tasks applying the translational operant platform touchscreen technology; the visual discrimination/acquisition task was used to assess the ability to perceive and distinguish visual(More)
The aims of this study were to investigate behaviour relevant to human autism spectrum disorder (ASD) and the fragile X syndrome in adolescent Fmr1 knockout (KO) mice and to evaluate the tissue levels of striatal monoamines. Fmr1 KO mice were evaluated in the open field, marble burying and three-chamber test for the presence of hyperactivity, anxiety,(More)
